- controls the output volume of the effect
- turns on a low-pass filter, cutting off the high frequencies
- controls the amount of fuzz
- controls the input level of the effect. At higher gain settings a lot of effects can go into overdrive or distortion.
The logical next step in fuzz tone after the Geranium Fuzz and it's '60's rock tone, the Hism Scism delivers the '70's tone and then some.
Driven by a pair of carefully selected silicon transistors, the Hism Scism is not the overly bright spitty fuzz that many people associate with a silicon-styled fuzz. It's very warm and very smooth. Like most Si fuzzes, it is capable of higher gain fuzz tones, but unlike many Si fuzzes, the "Scism" doesn't mind a bit if you'd rather not max out the fuzz. Compared to the Geranium Fuzz with it's harmonically rich upper-mids, the Hism Scism is slightly more scooped with a more robust and elastic bottom end.
The input control allows you to limit the signal entering the pedal resulting in a cleaner or more saturated fuzz tone. The output control sort of does the same thing, but in a different way. The combination of the two can provide unlimited shades of fuzz. It sort of tunes the bottom end. Want more bottom? Crank up the input. Less bottom? Back off on the input a little. The high cut switch is not exactly a tone control (though careful listening will yield some tone cut), it's actually added to allow you to match the fuzz to different amps. It's generally accepted that fuzz sounds better through Marshall type amps and harsh through Fender style. With the high cut switch engaged, the Hism Scism will sound just as sweet through your Fender! Of course it's true bypass with an LED and a DC jack.
